Field Resistance in DC Generator Formulas

Field Resistance is defined as the opposition offered to the current through the field winding, which is a coil of wire that produces the magnetic field in the machine. And is denoted by R_f. Field Resistance is usually measured using the Ohm for Electric Resistance. Note that the value of Field Resistance is always positive.
